To all whom it may concern:

lie it known that I, llosnrn E. CAMP,l a citizen of 4the United States, residing atWashington, in the county l oi Tazewell and State of Illinois, have invented cer- .tain new and useiul Improvementsin Portable Grain-y Dumps ;v and he does hereby declare that the yfollowing is a full, clear, and exact description of the invention, which will enable others skilled'in the art to which it appertains to make and use the same.

This invention pertains to improvements in portable grain' dumps.

The object of the invention'is to Vfurnish.tin-entirely new struclurein apparatus of this character and one that will takeup but little space. p

A further object is to construct a grain dump in which the mechanism for raising lthe wagon for dumping is also used for lowering the same. Y A

A still further and important object of the `present invention is to provide adiierent mounting and means .for handling'the conveyeror drag usually employed for receiving the grain'from the wagon. A

`In the appended drawings, Figure 1 is'a top View of my entire dump'as I 'prefer to construct it. Fig. 2 isa partial vertical end'section of the same. Fig. 3 is aver- .ticalcross section of laco'nveyer or drag showing manner of mounting it at Vone endand attaching power thereto. Fig. 4 is a perspective viewr of-.a portion of said conveyer showing a, squaredfshaftthereof. Fig. 5 'is a perspective view of a portion of a knuckle or universal jointused with the shaft shown in Fig. 4. Fig. 6 is a perspectivelview of aportion' of the conveyor showing the opposite ud from that shown in Figs. 3 'and 4 illustrating manner of pivotally supporting it. Fig. -7 is a `perspective View of an' automatic brake mechanism and throw-0H.' Fig, 8-is a perspective view of any adjustable hopper.' Fig. 9 is a perspectiveview'of a portion of the dump platformshowing part of my wagon raising mechanismv Fig. 10 is a longitudinalrsectiomof a reversing gear mechanism. Fig. -ll is a face view of thesame showing the inside'of a brake drum. i

The platform for'the wagon is'indicatedtby the letter A. and the approaches thereto by BL Running lengthwise of the platform A near each edge is a guide C consisting oi'a wooden bar or otherlike member by which to properly guide `the Wheels of the wagon to station the 'latterinproper position for the dumping operation. i These'saidl members a'rebette'l` shown in Fig. 2 in cross section and it is designed that the wheels run between tl1em.- Near the 'front end of the .plat-l form isa hole indicated at D situated midway between thc said guides C. At each side of-this hole and secured to the platform is a standard. E extending above thc platform about 18 inches andbelow the same 8 or l0 inches. rlhe said standards at their lower ends approach cach other as shownin Fig. Zend a bar F extending fromone to the other forms a support for two lazytongs G whose lowermost bars are pivoted on such bar F, the latter passingtherethrough. The said lazy tongs are of the nsualconstruction consisting of several pairs of the arms g as shown. n I g The pivots for the several pairs of arms consist of the bars H which are similar to F and connect the two lay-tong members, 4theends of said barsH projecting beyond the' said members and guided in grooves 65 Iin the adjacent faccs 0i. the standardsE which extend down-to the yfloor of the platform or further if desired. lCarried .at the. top of each-lazy-tongs is a horizontal bar J pivotedfat one end to `thebars of the tongs and'lthe other end supported by, friction roller 70v K on the opposite arms of said tongs whereby the latter may rise end fall and its arm extremities movev toward and away from one another. grids of these armslnust, of course, be free in order to` permit the tongs to spread as will be understoodand lit will 7 5 be seen' that since the said bar J is mounted in the manner described it will maintainV a horizontal posii I tion at alltimes regardless of tho jclevation itA may attain, the roller traveling beneath itkas the tongs rise and fall. The two bars thus mounted on their 80 respective tongs constitute supports for the fronty axle. of the wagon .which is indicated in broken lines in Fig. 1Ll Said bars areplaced suicently far apart to'fom' a steady support for the said axlevit being understood that both oi them travel upand downin i the same relation at all times'. Near the top of each. standard'E is an ear or lug at each side oi the groove l and on each is a grooved wheel L, L. Alsopn the er@ tension of the lowermost bar H between the standard and the lazy-tongs is a pair of similarly grooved wheels indicated by M and N.l A .cable O is attached at one' end to the supporting pin of the roller L and passes down beneath the ro1ler`N, thence up over the roller L anddown around the roller M, thence up again i g y over the roller L and iinally down to a winding drum P on a shaft Q journalcd beneath the platform in aA transverse direction. It will be seen that two cables are necessary, one boing for cach lazy-tongs as vshown and letters of reference correspond in like manner to both the cables and the rollers or wheels describedxiOC The lower ends of the cables` arc secured to the said drum I and are wound upon the latter and i'tn'vill be understood that when winding upon tho saidx drum 'thc tongs will be raised to any desired height to properly clcvul-e the wagon i`or'dun1ping the loadf The 105 *height to which the wagon is carriedinay be prodoteiniinculand set to stop at the desired point all of which will ho lr-scribed..

Tis loosely mounted the ir' fore mentioned. This nu-Tini;

revolution of the shaftV with the result that the worm S is driven in the opposite direction from what it was when raising the wagon. This motion reverses the direction of rotation o f shaft Q to unwind the cables and lower' the lazy-tongs. In connection with this mechanism l desire to provide means for automatically stopping the raising ,of the wagon and to accomplish this I attach a hook 34 to one of the 'bars of the lazytongs. Hung from this hook is a chain 35 terminating in a cable 36 which passesbeneatha pulley 37 below the said lazy-tongs, Fig. 7, thence over a pulley-38 to a pulley 39 and down' to connect with ,the lever U2.

i This is indicated partially in Figs.- -1, 2 and 9 but in fun Vin said Fig. 7. It will be lseen that as the wagonis raised-the cable. will be drawn upon at a. certain point to withdraw the pin 32 to release theshaftfIfas before ldescribedland the extent of pull uponsaid cable canbe -such that the shoerU will not be settoreverseahedirection of rotation o f the shaft, thatLope-rationbeing left to the: attendant who, after thejwagon-'s relieved of its load pulls the Vleverstill further to set the shoe and 1cause the piions torevolveithe said shaft T its other "direction to lower theswa'go -flfhave provided caster wheels for the front end of the A'platform A shownat 40 and also wheels 41 'at the rear to provide means for moreeasily transporting the dump `f lomfplace to place. In bringing -out my improved dump I desire to make it clrly understood that it is not the intention to confine myself to the exact means lshown and'described for assisting the lazy-tongsI in work as other construction may be employed to accomplish the same end.

The peculiar form of the membersJ on the tops ot the lazy-tongs `is of advantage since the axle cannot slip out and therefore no lock is needed for the wagon toprevent backward movement when dumping as in other forms of dumps. The reversing gear within the member U causes the wagon to be lowered muchfasterthan when in the raising act since the several pinions operating in connection with U compel this resultas will b`e readily understood. b
